Hi-tech Singapore is planning to roll-out a swarm of drones for tasks that include delivering parcels, inspecting buildings and providing security, but safety and privacy concerns mean the initiative may hit turbulence. Companies have already started testing the devices for commercial use, mainly in an area of over 200-hectares(500-acres) dotted with high-rise buildings and shopping malls, specially designated by the government for the trials.

North and North-west Delhi residents may now have fewer-power-cuts as the power-distribution company in that area could employ drones for faster maintenance of its distribution network to offer "better and accurate" service resolutions to its seven-million consumers in the national-Capital, said an official. The company used nano drones with a flying capacity below 200-feet with permission from police and local authorities, an official said.

India's new drone regulations are set to change the landscape of the real estate sector from December, as the 3-D mapping of properties will not just become powerful tool for marketing but will further boost transparency and accountability, industry experts say. The commercial use of drones under the recently announced DGCA norms has been made legal from December 1.
